Intrusion detector "Zebra-30(5,8)V (fan)".

They are used for protection of separate sections of the perimeter, where the use of two-position detectors is difficult or impossible, for example, dead ends, swampy areas, ravines, crossings over the fence, storage areas, tunnels, overpasses, overpasses, etc.
The main distinguishing feature of ZEBRA-30(5,8) detectors is the operating frequency of 5.8 GHz, which provides the detectors with the following advantages:
- insensitivity to atmospheric precipitation (rain, snow);
- increased resistance to the presence of grass cover (the permissible height of the cover is 0.3 m);
- increased resistance to the presence of individual plants up to 0.5 m high;
- increased resistance to vibrations of the support
